Change your call to:

<!--#var "sixfield_page(_.None,_,title='Authors and their works',
                          body=authors_body())"-->

When you call a DTML method in an expression from DTML, you must pass
"_.None,_" as the first two parameters if you want the current namespace to
pass through.  Otherwise, sixfield_page will not have access to any
variables other than 'title' and 'body', period.

I believe there's some more detail on how this works in the DTML reference
manual.
